DANIEL L. STOUCH, OF YORK, PENNSYLVANIA.

TIRE.

Application led April 1.3,

To all 'LU/wm it may concern Be it known that I, DANIEL L. Sronon, acitizen of the United States, residing at York, in the county of Yorkand State of Pennsylvania, have invented certain new and uselulImprovements in Tires, ot which the following is a speciiication.

This invention relates to tires Ytor vehicle wheels, and moreparticularly to resilient, airless tires.

An object of the invention is the provision of a tire casing having aninwardly extending, centrally disposed rib provided with means forlocking the beads ot the tire in position.

A Vfurther object is the provision ot a rib ot varying degrees ofhardness.

A further object is the provision ot a tire of the type described,wherein the fabric er;` tending through the side walls is depressed inthe crown portion of the tire into the top of the rib or iiller block tostrengthen the rib and hold the fabric in proper position.

In the accompanying drawings, I have shown one embodiment of theinvention. In this showing.

Figures l is a side elevation ot a portion of the tire, parts beingshown in sectioinand,

Figure 2 lis a transverse sectional view on line 2--2 of Figure l.

Referring to the drawings, the reference numeral l designates the sidewalls or wings ot a tire similar in external appearance and shape` tothe ordinary pneumatic tire cas ing. These side walls are provided witha crown f2 which is thickened to ttorin a tread 3. The usual fabricstrips e extend through the side walls ot the tire and surround beads 5,arranged at the lower end oit each side wall. Substantially` centrallyof the crown portion ot the tire, there is provided an inwardlyextending portion G and the fabric passing through the crown portion iseX tended inwardly through this portion, as indicated at i'. rib orfiller bloclr extends inwardly troni the center o'l' the crown of thetire to the base and is adapted to rest upon the riin. As shown, thisrib comprises a plurality ol sections of varying degrees ot hardness. Anupper section 8 of relatively soft rubber is secured to the rubber'forming the casing and a harder section 9 is arranged below therelatively sott rubber. This harder section may be provided with afillingot linters, silk, or other libres to produce the proper degree othardness. The

lower end il() of the rib is 'formed of a relatively haiid compositionand is provided with rediilced portion 'forming shoulders ll which areadapted to rest upon the top of heads, the width ot the extreme end l2*eng equal to the distance between the inner edfj f' he beads 'when thetire arranged on the i.

The rib provided with a layer of rubberized fabric i3, arranged. nearKits edge and extending through the harder rubber section to helpstitifen it, and prevent the tire trom swaying when the wheel is turned.

By means ot the construction disclosed, I provide an airlcss tire havingthe resiliency of a pneumatic tire and elimiinitiner the objections oiithe pneumatic tire. The inwardly extending po;' 1 ot -the tabrirI bindsor locks the rib to the casing and permits the use et a heavier tread.Iii tires of this type. it has heretofore been the tendency of the treadand rib to separate from each other. which is prevented by theconstruction disclosed. i

The provision of shoulders ll securely lor-lts the parts in position onthe rim of the wheel and prevents the beads 'from becoming disjrilaccdthereby permitting the tire to come ofi the wheel. In a pneumatic tire,the pressure ot air within the tube securely holds the beads in place.but in the construction ot airless tires heretofore j'noposed, nopositive means have been ifuovided Ytor retaining the beads o'l the tirein position.

A further advantage ot the present construction is the use oit a rib olivarying degrees oit hardness, whereby sutlicient strength is al"-Y."'orded to support the load and a t the saine time` the sott rubberportion S affords the necessary resiliency to produce the eii'ec't olf apneifunatic tire.

lt is to be understood that the 'form ot my invention herewith shown anddescribed to be taken as a preferred example ot the saine.. and thatvarious changes in the shape,

e, and arrangement ot parts may be resorted to without departing fromthe spirit of the invention or the scope ot the sublioined claims.

I-Iaving thus described my invention, I claim:

l. In a device ot the character described, a casing having a crownportion, said crown portion i'ieing provided with anA inwardly extending portion, l'abric reeniiorcing arranged in said casing and extendingtl'irough said inwardly extending portion, and a rib Aformed on saidinwardly extending portion and projecting toward the base of the tire.

2. in a device of the character described, a casing having a crownportion, said `crown pvr lon being provided with an inwardly extendingportion, Afabric reenforcing arranged inl said casing andextendingvthrough said inwardly extending portion, and a rib iornledonsaid inwardly extending portion and projecting toward the base of thetire, the lower end ot said rib being reduced to forni shoulders adaptedto engage the inner 'edges and top of the tire beads when the tire nis'in position.

in a device of the character described.

portion being provided with an inwardly extending portion, fabricreenforcing arranged in said casing and extending through said inwardlyextending portion, and a rib i'rrrned on said inwardly extending portionand `projecting toward the base of the tire, said rib being formed of aplurality of rubber sections ot varying degrees of hardness and beingprovided with shoulders upon its lower end adapted to engage the beadsof the tire when in position; y ln testimony whereofl aiiix my signaturein presence oi" two witnesses.
